Should i leave network selection on "auto" outside of luxembourg, does it make any difference if i choose manually?

In automatic mode, your phone connects directly to the most suitable partner network, ensuring the best availability and an optimized connection.

In manual mode, you can select a specific network, but this may result in:

• a loss of connection if the selected network is not optimal or out of coverage
• variable service quality depending on agreements between operators
• the need to manually switch networks when you move.
